3 Claims.

. This invention relates to screen frame structures, andmore particularly to an improvement in the method of securing such structures to the inner side of metallic window frames.

An. object of the invention is to provide means whereby window screens such as are mounted on the inside of the new swinging metal windows, may be quickly installed .and easily removed.

A further object of the invention is to provide a screen suitable for inside mounting which may be securely anchored in place Without the use of screws or bolts.

A further object of the invention is to provide a screen structure which may be prefabricated at the factory in standard sizes without necessitating the installation of new equipment or altering the usual production methods.

vertical axis.

These and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is an inside plan view of a standard window having mounted thereon a screen made in accordance with the invention.

Fig. 2 is an enlarged, partial side view of Fig. 1.

Fig. 3 is a front plan view of a screen framework made in accordance with the invention.

Fig. 4 is a side view of the screen frame shown in Fi 3.

Fig. 5 is a bottom view of the invention.

Fig. 6 is .a cross sectional view of the invention on line 6-6 of Fig. 3.

It has become the practice to install screens on the inner side of the new metallic window frames, the windows of which swing outward about a Such screens are held in place by means of brackets, bolts, and/or removable pins. However, such methods of fixation have not been entirely satisfactory in that ease of installation and removal are of prime importance, in addition to the requirement of a snug fit whereby to preclude entry of insects and the like between the screen and window frame.

This invention is directed to the production of a screen which may be inexpensively manufactured and one which may be quickly installed or removed by the average housewife.

As shown in Fig. 1, a screen to is positioned on the inner or room side of window frame H. The window frame II is of the conventional metal type which has associated therewith a metallic sash which opens outward when the opening mechanism I2 is actuated through control crank As shown in Figs. 3, 4, 5, and. 6, a lip 14 is provided in the inner or room side of lower edge by the wedging action between lip Hi and the 5 offset I! provided where the crank shaft housing I8 emerges from the opening mechanism unit ii.

The upper end of the screen is held in place by any suitable locking means such as the one shown in which arm 19 is pivotally mounted to 10 the screen frame as at 29. A cooperating member 2| having an arm-engaging member 22 is fastened to the window frame I l by any suitable means such as by screws 23.

Screens embodying the invention may be manufactured at the factory, since the framework II and window operating mechanisms I2 .are standard in sizes andalways in the same relative positions.

A screen made in accordance with the inven- -It is to be understood that any suitable type of holding means may be used in lieu of the latch clip combination herein disclosed without departing from the spirit of the invention.

Due to the ease with which lip l4 may be formed in lower edge 15 of a screen frame, such an operation may be performed even after the screen has been completed, which greatly enhances the utility of the invention.

It is not necessary to mar the interior window frame finish with a plurality of holes, screws or brackets in order to install a screen made in accordance with this invention since only one latch member is needed on the window frame in order to maintain lip M of screen II] in proper engagement with offset 11 of the window opening mechanism crank housing which is standard equipment on all those windows where this type of screen is required or used.

A decided advantage of a lip, as herein disclosed, over protruding pins as are commonly 50.,

used is the durability of the lip, which because of its being punched with reinforced edges becomes stronger than the screen framework proper. The lip cannot be broken off by an accidental bump nor is its efliciency impaired in any way should foreign matter find its way into the lip opening since only the outer edge of lip l4 bears against the retaining offset of the opening mechanism. The formation of the sheet metal screen frame into the protruding abutment or lip l4, imparts a degree of resiliency to the lip l4, reinforced by the upturned lower edge of such lip, whereby to effect a snug anti-rattle fit of the screen frame between the window frame H and the opposed abutment edge or ledge H on the housing [8.

The window frame ll may comprise a unitary structure of one or more members 30, 3|, 32 and 33, each having a face coplanar with similar faces of each of the other of such members or parts 30, 3i, 32 and 33, thus providing a continuous flat circumferential face extending about the central opening in the frame and upon which face a similar coplanar peripheral face 34 of the screen may be snugly fitted or held. Consequently, substantially a firm flat or coplanar contact, as indicated at 35 of Fig. 2, is made by the screen frame face 34 and window frame face 33, 3|, 32, 33.

By reference to Fig. 4, it is obvious that the sheet metal frame of the screen is formed so as to provide an encircling or peripheral hollow box or casing comprising front and rear walls 36 and 37 respectively, an edgeforming wall 38 and an inturned wall 39. The lip I4 is formed from the sheet metal disposed adjacent the junction of the rear wall 31 and the bottom portion of the edge wall 38. A slit is formed in the bottom edge wall, a slight distance inward from the rear wall 31, and some of the metal between the slit and the corner or junction of the indicated walls, is folded over or pressed. into contact upon the inside face to of the wall M as shown in Fig. 6. This operation of slitting and so forming the indicated parts may be accomplished by a single punching and forming operation. Thus the protruding lower edge of the lip I4 is provided with a rounded bead-like formation that not only reinforces the lip, but also prevents the presentation of a sharp edge upon which a person might be injured. The sheet metal, by reason of its flexibility, readily stretches intermediate the ends of the slit to permit attaimnent of the indicated formation.

What is claimed is:

1. A screen adapted for association with a window comprising a frame having a window control housing spaced from the mean plane of said window frame, said screen comprising a sheet metal screen frame having a hollow sheet metal casing providing contiguous angularly disposed wall portions and having a slit formed in one of said wall portions, said slit extending in substantial parallelism with the other of said wall portions, the sheet metal intermediate said slit and other wall portion being deformed so as to contact the inner face of said other wall portion and being, together with said contacting wall portion protruded outwardly beyond the adjacent portions of said other wall portion, whereby to provide a reinforced outwardly projecting abutment lip integral with said sheet metal frame, said abutment lip adapted to abut against said housing for holding said screen in place relative to and in contact with said window frame.

2. A screen adapted for association with a window frame including a window operator mechanism housing in spaced relation thereto, said screen comprising a sheet metal frame having spaced parallel inner and outer faces and an integrally formed bottom substantially at right angles to said inner and outer faces, a slit provided in said bottom intermediate the inner and outer faces and in substantial parallelism thereto, said slit being expanded outward to deform the inner face and that portion of the bottom intermediate said slit and said inner face, to provide an abutment lip extending laterally outward from the mean plane of said inner face and integral with said frame, the lower edge of said screen being adapted to be wedged between said window frame and said housing member by interaction of the lip with said housing member.

3. A screen adapted for association with a window frame including a window operator mechanism housing in spaced relation thereto, said screen comprising a sheet metal frame having spaced, parallel sides and a bottom integrally formed at right angles thereto, a slit provided in said bottom adjacent to and parallel with a side wall, said slit being expanded outward to deform that portion of that side wall adjacent said slit whereby to provide a. laterally extending abutment lip integral with said frame, said lip adapted to contact said housing whereby said screen is wedged in place between said window frame and its associated control mechanism.
